This plugin adds emails to a mailing queue instead of sending immediately. This speeds up sending forms for the website visitor and lowers the server load. 
Emails are stored as files which are deleted after emails are sent.
You can send all outgoing emails via an SMTP server or (the WordPress standard) PHP function <a href="http://php.net/manual/en/function.mail.php" rel="nofollow ugc">mail</a>, and either use <a href="https://codex.wordpress.org/Function_Reference/wp_cron" rel="nofollow ugc">wp_cron</a> or a cronjob (if your server/hoster supports this) to process the queue.
Plugin requires PHP 5.4 or above.
Tools:
<ul>
<li>You can send test mails to test your setup.</li>
<li>You can process the mailing queue manually instead of waiting for cronjob.</li>
</ul>
Supervisors: 
* You can display basic informations about mail processing performances 
* You can display the mailing queue in the backend to see emails that will be sent with next processing. 
* You can display the invalid mails and delete or retry them. 
* You can display the sent mails and delete them.
Coming soon:
<ul>

</ul>
